A sleeve shaped protector for a portion of a limb is manufactured from a sheet of cloth comprising a core of resilient, porous material laminated upon both faces with a sparse fabric. The sheet is cut to suitable size and rolled into a tubular member, whereupon a strip of fabric, being substantially non-resilient in its transverse direction is laid to cover the joint between the meeting edges of the sheet. The strip and the sheet are then sewn together using a machine having at least two needles to each side of the joint, the machine further having means for criss-crossing the threads from the needle to opposite sides of the joint, across the latter, at the face of the cloth remote from the strip. |
